This can be implemented by modifying "AMRAudioRTPSink" to:
1/ Remove the reimplementation of the virtual function
         frameCanAppearAfterPacketStart()
(because the default version of this function returns "True".)
2/ Implement the virtual function "frameSpecificHeaderSize()" in 
addition to "specialHeaderSize()" (defined in"MultiFramedRTPSource"), and
3/ Modify its implementation of the virtual function 
"doSpecialFrameHandling()" to use the following functions
         setFrameSpecificHeaderWord()
and/or
         setFrameSpecificHeaderBytes()
in addition to
         setSpecialHeaderWord()
and/or
         setSpecialHeaderBytes()

If someone ends up doing this, please send us the patch.  Otherwise, 
I may someday end up doing this myself (although this may end up 
being low priority unless it's part of a funded project).
